How do I decode the \2 in this? I am creating types through this

simple. Any ideas?

[LLVMdev] alloca & store generation
After looking at this problem longer, I believe that there is something
wrong with the disassembler. When I run my transformation and then
disassemble the output, I get bytecode that looks like:

entry:
alloca int ; <int*>:0 [#uses=3]
alloca sbyte** ; <sbyte***>:0 [#uses=3]

[LLVMdev] need help understanding getelementptr assembler instruction
I am trying to understand the hello word assember example. This is
my version:
%str1 = internal constant [13 x sbyte] c"Hello World\0a\00"
declare int %printf(sbyte*, ...)
implementation ; Functions:
int %main() {
%str2 = getelementptr [13 x sbyte]* %str1, long 0, long 0
call int(sbyte*, ...) *%printf(sbyte* %str2)
ret int 0
}
Why is getelementptr being given two "long 0" indices?...

[LLVMdev] Linking strncpy

aborting or giving incorrect results; however, if I disassemble the
LLVM bytecode and recompile with GCC, everything works fine.
I encountered the following error when running lli with

"Tried to execute an unknown external function: sbyte * (sbyte

Strncpy is used as part of my compiler's run-time library, and it was
compiled with the C-frontend for LLVM. Looking at the assembly, the
function is declared at the top of the file;

[LLVMdev] Re: Hide visible string in variable
...OR and then write it back. But for this case, I don't know how to do that. Maybe I am not familar with STL. I really need your help. Sorry again.
for C level,
char a[]="global string test";
for(i=0;i<strlen(a);i++){
a[i]= a[i]^RANDMON;
}
For llvm,
%a = internal global [20 x sbyte] c"global string test\0A\00"
Would you mind telling me how to do it.

[LLVMdev] What's the meaning of [0 x sbyte*]?

%tmp.24 = getelementptr [0 x sbyte*]* %sys_errlist, long 0, long %tmp.23 ; <sbyte**> [#uses=1]
